Filed: 1988-07-22
Abstract: PURPOSE: To respectively conduct the opening and closing movements independently by arranging a flow restriction member in the flow path where pressured gas for urging the valve closure member against the valve seat is made to flow. CONSTITUTION: Gas flows through a port 12, a pipe 13 in between valve seats 18, 20 in the non-agitating condition of a second magnetic control valve D. Then the gas flows into a flow path 24 through a flow path 26 having a restrictor 28.

Title: Zero cross switching relay
Inventor: SATE TOYOFUMI
IPC: H01H47/00
Filed: 1992-07-10
Abstract: PURPOSE:To obtain the zero cross switching relay with less heat evolution from which noise hardly takes place with simple configuration. CONSTITUTION:A contact 20 of an electromagnetic relay and a 2-way thyristor 21 of light trigger type are connected in parallel, and after the contact 20 is opened, the thyristor 21 is subject to zero cross turn-off. When the thyristor is turned on and a voltage between output terminals 3,4 is dropped, an optical signal of light emitting diodes 18,19 is lost, a photo transistor(TR) 14 is turned off and power is supplied to a coil 15 of an electromagnetic relay and a light emitting diode 16 to allow the thyristor 21 to be in zero cross turn-on. As a result, since a main current is obtained via a contact of the electromagnetic relay, heat evolution is less and since turning-on and turning-off are implemented in the vicinity of a zero cross point, noise production is less and the relay is manufactured inexpensively with simple configuration.

Title: Encoder circuit
Inventor: ARAKAWA MASAO
IPC: H03K3/0231
Filed: 1983-09-30
Abstract: PURPOSE:To eliminate the need for provision of a phase difference of 180 deg. to an optical signal by deciding a threshold value at an amplifier having a feedback diode and an automatic threshold value set circuit so as to compare the optical signal with the value in detecting the optical signal. CONSTITUTION:A photodetector 1 converts the optical signal into an electric signal, which is inputted to an amplifier 2. Moreover, the input range of the amplifier 2 is expanded by the feedback diode 3. Then the automatic threshold value set circuit 4 holds a peak voltage of an output of the amplifier 2 and outputs a value being a half the held peak voltage so as to use it as a threshold value of a comparator 5. The comparator 5 has a hysteresis characteristic and converts stably the input into a pulse voltage. Thus, it is not required to provide a 180 deg. phase difference to an encoder circuit and it is not necessary to provide two fixed slits and two photodetectors are not required and only one photodetector is enough for the purpose.

Filed: 1986-08-06
Abstract: PURPOSE:To easily and exactly execute a detecting operation by constituting the titled device by sharing one piece of switch member to the detection of the device existence of a developing device, and the detection of the shelf-life termination of the developing device. CONSTITUTION:A circular arc cam plate 47 is a member which is displaced in accordance with the advance of the shelf-life of a developing device. When a developing device B whose shelf-life is not terminated is installed or it is under an installing state, the large diameter circular arc cam surface 47a of the outside periphery of the circular arc cam plate 47 of the developing device B side has an interference relation to the actuator 48a of a microswitch 48 of an image forming device body side. Therefore, by pushing up the actuator 48a, the microswitch 48 is held in an ON state. When the developing device B is used for a long period, and by following it, the circular arc cam plate 47 turns clockwise successively and a rotational angle attitude is varied, and the prescribed shelf-life is terminated, the large diameter circular arc cam surface 47a of the circular arc cam plate 47 does not correspond to the actuator 48a of the microswitch 48 and has a non-interference relation. In such a way, the switch 48 is held in OFF.

Title: Manual focusing mechanism
Inventor: NUMATA KIYOSHI
IPC: G02B7/00
Filed: 1984-09-04
Abstract: PURPOSE:To simplify a mechanism by forming an electric focusing mechanism and a manual focusing mechanism as independent driving systems. CONSTITUTION:When a turning knob 10 is rotated manually, a movable chassis 2 is moved in the arrow B direction and the electric focusing mechanism mounted on the movable chassis 2 is also moved in the same direction, so that a driving arm 23 engaged with a screw 14A part of a driving shaft 14 is moved in the same direction. Since a lever 24 rotates in the clockwise direction, a lens cylinder body 30 moves in the arrow D direction and focusing can be attained manually. Thus, the manual focusing mechanism is formed as a driving system independent from the electric focusing mechanism, so that the whole mechanism can be simplified by omitting complex mechanisms such as gear change and a clutch.
